It seems the reason your process-level isn't returning any <li> tags
is because there isn't a level 3. What's happening is you are
outputting the <ul> before checking to see whether there is a value.
Yes, I should have made clear that I know I needed a test, but just
didn't know *how* to do it.
Alas the below doesn't quite work. Besides needing to change the "<"
to "<", my level 2 bullets aren't getting applied now.
I think what you want to do is check to see if:
<xsl:if test="@level < following-sibling::bullet[(_at_)level][1]">
<ul>
<xsl:apply-templates/> <-- You'll have to edit this
</ul>

A simple XSLT convert Apple Keynote presentation files to S5, the

Because of limitations in the Keynote file format, I have relied on the
new
grouping functionality in XSLT 2.0. As such, you should use Saxon 8 to
run it.
